Description
This invention relates to a hydraulic setting tool for packers and bridge plugs. More specifically, this invention relates to a hydraluic setting tool for a bridge plug for use in geothermal steam producing wells.
Hydraulic setting tools for packers and bridge plugs are well known in the art. Some examples of prior art hydraulic setting tools for packers and bridge plugs are shown in U.S. Pat. Nos. 4,436,149, 4,441,552 and 4,516,634. However, such prior art hydraulic packer and bridge plug setting tools are either complex in construction and/or operation or require the use of balls or plugs to be pumped through the tubing string for the actuation of the setting tool in response to hydraulic fluid pressure in either the tubing string or annulus between the tubing string and well casing in which the packer or bridge plug is being set.
In steam producing geothermal wells or in highly deviated wells it is desirable to have a hydraulic setting tool which is simple in construction and actuation, does not allow steam from the well or well fluid to flow into the tubing string while the packer or bridge plug is being run into the well, does not require either rotational or longitudinal movement of the tubing work string or drill pipe to actuate the setting tool, and does not use balls or plugs to actuate the setting tool.
The present invention is directed to a hydraulic setting tool for packers and bridge plugs which is simple in construction and actuation, does not allow the flow of fluids into the tubing string upon which the setting tool and packer or bridge plug is being run into the well, does not require either rotational or longitudinal movement of the testing work string or drill pipe to actuate the setting tool, does not use balls or plugs to actuate the setting tool, and allows circulation of the well fluid after the packer or bridge plug is set. The hydraulic setting tool of the present invention comprises an adapter, housing, piston, piston sleeve and shear sleeve rod.
FIG. 1 is a cross-sectional view of the hydraulic setting tool of the present invention connected to the upper portion of a bridge plug.
FIG. 1A is a cross-sectional view of the remaining portion of the bridge plug shown in FIG. 1.
Thehydraulic setting tool 10 of the present invention is shown in FIG. 1 in its preferred embodiment.
Thehydraulic setting tool 10 comprises anadapter 12,housing 14,piston 16,piston sleeve 18 andshear sleeve rod 20. Also shown in FIG. 1 is the upper portion of abridge plug 200 to which thehydraulic setting tool 10 is connected. Thebridge plug 200 is similar in construction and operation to the bridge plug described and shown in U.S. Pat. No. 4,185,689. Thebridge plug 200 shown in FIG. 1 has a flatannular surface 202 onupper slip support 204 for a portion of thehydraulic setting tool 10 to bear upon during actuation of the setting tool. Thebridge plug 200 also includesupper slips 208 andlock ring 203 contained withinupper slip support 204.
Theadapter 12 of thehydraulic setting tool 10 comprises a cylindrical annular member having, on the exterior thereof firstcylindrical surface 22, secondcylindrical surface 24 havingannular recess 26 therein containing annular elastomeric seal means 28, threadedsurface 30 and thirdcylindrical surface 32 and, on the interior thereof, threadedbore 34, first frusto-conical bore 35,first bore 36, second frusto-conical bore 37,second bore 38, frusto-conical surface 40, a plurality ofaxial passageways 42, threadedblind bore 43, andsecond bore 44. Theadapter 12 further includes a plurality ofapertures 46 extending from thirdcylindrical surface 32 tosecond bore 44.
Thehousing 14 of thehydraulic setting tool 10 comprises an elongated annular cylindrical member having, on the exterior thereof,cylindrical surface 48 and, on the interior thereof, firstcylindrical surface 50 which sealingly engages annular elastomeric seal means 28 ofadapter 12, threadedbore 52 which releasably engages threadedsurface 30 ofadapter 12, first frusto-conical bore 54,second bore 56, second frusto-conical bore 58 andthird bore 60.
Thepiston 16 of thehydraulic setting tool 10 comprises an annular cylindrical member having, on the exterior thereof, firstcylindrical surface 62 havingannular recess 64 therein, secondcylindrical surface 66 having a plurality ofrecesses 68 therein containing annular elastomeric seal means 70 which slidingly, sealingly engagesecond bore 56 ofhousing 14 and threadedsurface 72 and, on the interior thereof, bore 74 having a plurality ofannular recesses 76 therein containing annular elastomeric seal means 78. Thepiston 16 further includes a plurality ofshear pins 79 having a portion thereofengaging apertures 46 ofadapter 12 and a portion thereof extending intoannular recess 74 ofpiston 16.
Thepiston sleeve 18 of thehydraulic setting tool 10 comprises an elongated annular cylindrical member having, on the exterior thereof,cylindrical surface 80 and, on the interior thereof, threadedbore 82 which releasably engages threadedsurface 72 ofpiston 16 and bore 84.
Theshear sleeve rod 20 of thehydraulic setting tool 10 comprises an elongated cylindrical member having threadedupper end 86,cylindrical surface 85 which slidingly, sealingly engages annular elastomeric seal means 78 ofpiston 16,annular flange 87 on the bottom end thereof, and blind threadedbore 89 therein. Theshear sleeve rod 20 further includes shearrod adapter end 91 having threadedend 93 which releasably engages blind threadedbore 89 ofrod 20 andannular flange 88 thereon andshear sleeve adapter 90 which has one end thereof abuttingannular flange 85 ofrod 20 while the other end thereof abutsannular flange 88 of shearrod adapter end 91 and threadedexterior surface 92 which releasably engagesshear sleeve 206 ofbridge plug 200.
Referring to FIG. 1A, the remaining portion of thebridge plug 200 is shown. Thebridge plug 200 includesupper slip wedge 210,packer element 212lower slip wedge 214,slips 216,lower slip support 218,catcher assembly 220, push outplug assembly 222, andmandrel 224.
Referring again to FIG. 1, the operation of thehydraulic setting tool 10 of the present invention will be set forth.
Thehydraulic setting tool 10 is connected to a work string of tubing or drill pipe byadapter 12 threadedly engaging one end thereof. Thebridge plug 200 or packer is retained upon thehydraulic setting tool 10 by shearsleeve rod 20 havingshear sleeve adapter 90 threadedly engagingshear ring 206 ofbridge plug 200.
After thehydraulic setting tool 10 havingbridge plug 200 connected thereto is assembled on the work string of tubing or drill pipe, thehydraulic setting tool 10 andbridge plug 200 are run into the well to the desired location at which the bridge plug is to be set.
To actuate thehydraulic setting tool 10 fluid pressure in the work string of tubing or drill pipe is increased until the fluid pressure acting on the upper end ofpiston 16 is great enough to cause theshear pins 79 to shear thereby allowingpiston 16 havingpiston sleeve 18 connected thereto to move downwardly causing the lower end of thepiston sleeve 18 to spreadlock ring 203 outwardly so thatsleeve 18 may pass therethrough to bear on flatannular surface 202 ofupper slip support 204 ofbridge plug 200. Thepiston 16 andpiston sleeve 18 continue to move downwardly causingupper slips 208 to be cammed into engagement with the casing (not shown) in the well bore.
When theupper slips 208 engage the casing in the well bore, further downward movement of theupper slips 208 is prevented. After theslips 208 engage the casing in the well bore, the relative movement between thepiston 16 andadapter 12 havinghousing 14 andshear rod 20 secured thereto occurs because the increased fluid pressure causes the force acting upwardly onadapter 12,housing 14 andshear sleeve rod 20 to be greater than the force acting downwardly onshear sleeve rod 20. At this point, the downward movement ofpiston 16 andpiston sleeve 18 generally ceases and theshear sleeve rod 20 moves upwardly relative to thepiston 16 andpiston sleeve 18 until the force acting onshear sleeve 206 of bridge plug viashear sleeve rod 20 causes theshear sleeve 206 to shear thereby releasing theshear sleeve rod 20 from theshear sleeve 206 andbridge plug 200. During the relative upward movement of theshear sleeve rod 20, since theshear sleeve 206 of thebridge plug 200 is attached to themandrel 224 of the bridge plug which, in turn, is attached tolower slip suport 218 of thebridge plug 200, thelower slips 216 are brought into engagement with the casing in the well which thereby prevents any further upward movement of theshear ring rod 20 until theshear ring 206 shears thereby releasingrod 20. At this point, thebridge plug 200 is set in the casing in the well and the hydraulic setting tool is released therefrom when sleeve 206 shears.
At this time, sand or gelled fluid can then be placed on top of plug or the well can be circulated with fluid from the bridge plug up by pumping fluid through the tubing work string or drill pipe throughpassageways 42 inadapter 12, through the annulus between thehousing 14 andshear sleeve rod 20,past piston 16 which is abuttingannular flange 87 onshear sleeve rod 20 and out the annulus formed betweenthird bore 60 ofhousing 14 andcylindrical surface 80 ofpiston 16 over the top of bridge plug 200 into the casing in the well bore.
Thus, it can be seen from the foregoing that the construction of thehydraulic setting tool 10 is simple, that the operation of thehydraulic setting tool 10 is simple, that fluid flow through thehydraulic setting tool 10 is prevented by thepiston 16 andshear sleeve rod 20, that no balls or plugs are required to be pumped through the tubing work string or drill pipe to be able to actuate thehydraulic setting tool 10, and that no rotation or longitudinal movement of the tubing work string or drill pipe is required to actuate thehydraulic setting tool 10, and that the fluid in the annulus between the tubing work string or drill pipe and the casing in the well bore may be circulated out if desired.
